DATA_LRU_LISTS <number of lists>

Note: The LRU algorithm is no longer used for the data cache.

To reduce mutex contention, the cache control model permits the configuration keywords DATA_LRU_LISTS and INDEX_LRU_LISTS to specify how many LRU lists are maintained for data cache pages and index cache pages, respectively.

On Windows, Solaris, and AIX, the default is based on the number of available CPUs on the system and the CPU limit specified in the license file. Otherwise, DATA_LRU_LISTS defaults to 4.
